A silicone rubber [ν = 0.49] wristband has an initial length of 106 mm and a width of 9 mm. If the wearer stretches the length by 27 mm while putting it on, what is the corresponding change in width?

A silicone rubber [ν = 0.49] wristband has an initial length of 93 mm and a width of 11 mm. If the wearer stretches the length by 22 mm while putting it on, what is the corresponding change in width?

An aluminum bar with a 1.00-in. gage length, 0.150-in. width, and 0.090-in. thickness is loaded in tension. At the proportional limit, a load of 860 lb elongates the gage length by 0.00598 in. and reduces the width by 0.0003 in. Determine the modulus of elasticity.

Bolt holes with a diameter of 1.125 in. are punched into structural steel members that have a thickness of 0.40 in. If the shear stress in the steel is 38 ksi, determine the bearing stress between the punch and the steel.

A rigid steel bar is supported by three rods, as shown in the figure. There is no strain in the rods before the load P is applied. After load P is applied, the normal strain in rod (2) is 1140 μin./in. Assume initial rod lengths of L1 = 65 in. and L2 = 168 in. Determine the normal strain in rod (1).

A cylindrical steel rod with a diameter of 0.525 in. and a length of 4.0 in. sits on a base that has a 0.55-in. gap at its middle. If a 12.9-kip load is applied above the gap, determine the shear stress in the rod.

A thin polymer plate PQR is deformed so that corner Q is displaced downward by a distance L = 0.95 mm to new position Q’ as shown. Determine the shear strain at Q’ associated with the two edges (PQ and QR).

If a uniform distributed load w = 51 lb/ft and concentrated load P = 490 lb are applied to the beam as shown, determine the vertical reaction force at B. Assume a = 12.0 ft and b = 4.8 ft.

A rigid steel bar is supported by three rods, as shown in the figure. There is no strain in the rods before the load P is applied. After load P is applied, the normal strain in rod (2) is 1100 μin./in. Assume initial rod lengths of L1 = 60 in. and L2 = 162 in. Determine the normal strain in rod (1).

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown. If P = 32 kN, Q = 21 kN, and R = 26 kN, determine the absolute value of the axial load in rod (3).
